Hale said initially, the report he got about the play from Allen Campbell, who looks at the replays in the Arizona clubhouse, was that Maybin's hand got in before the throw.
"So I told the umpire, OK, we're good, and I sat down here in the corner," Hale said. "And then the phone rang and it was Allen and he said, 'Review it, review it, he came off.'"
At that point, Hale had already told the umpire they weren't going to review it and the hitter was in the batter's box and the pitcher was on the mound, so Hale thought it was too late to challenge.
Between innings, Hale spoke to the umpire crew and they informed him that for future reference he could have taken more time to decide.
"The mistake there was not being patient and letting Allen look at the whole play," Hale said. "That hasn't happened this year. What ends up happening is, you have, really, as much time as you want. The umpires are very patient about it. It's just a lesson to be a little more patient, maybe."
